The Value of Surveillance Imaging of Oral Squamous Cell Carcinoma.

The evaluation of surveillance imaging of OSCC patients is a difficult task physicians have to face daily. Multiple patients experience a recurrence of this disease, which underlines the importance of regular patient monitoring programs. Our study analysed the value of surveillance imaging, such as computed tomography (CT) and nuclear magnetic resonance imaging (NMRI), as a patient monitoring programme and its effectiveness in achieving improvement in early recurrence detection.

Perioperative anticoagulation in head and neck free flap reconstructions: Experience of an anticoagulative scheme and its modification.

Objectives: Microvascular anastomoses in microvascular reconstructions induce rheological changes in the anastomosed vessels and are usually counteracted by anticoagulative medication. There is no regimen commonly agreed on. This study provides an easy to use anticoagulative regimen.

The COVID-19 pandemic and its possible impact on the treatment of odontogenic and intraoral abscesses.

Most odontogenic and intraoral abscesses can be treated on an outpatient basis with local anesthesia. However, severe disease progression may require an incision under general anesthesia (GA) with postoperative inpatient treatment. This study aimed to evaluate the first "COVID-19 year" in Germany and compare the first "COVID-19 year" with the two previous years.

E-scooter-related craniomaxillofacial injuries compared with bicycle-related injuries - A retrospective study.

The aim of the study was to compare incidences and types of injury incurred between e-scooter crashes and bicycle crashes. This retrospective study included all victims of e-scooter crashes who were treated in the department of oral and maxillofacial surgery during a 12-months interval.A comparison was made with a cohort of patients who underwent bicycle crashes.

Temporal Tendinitis in Craniomandibular Dysfunction (CMD) - Does it Really Exist? A Temporomandibular MRI Investigation.

Objectives: The aim of the study was to analyze the role of temporal muscle and particularly tendon pathology in patients suffering from craniomandibular dysfunction (CMD) using magnetic resonance imaging.

Materials And Methods: Retrospective analysis of MRI examinations was carried out with regard to temporal muscle fibrosis and fatty degeneration and particularly temporal tendon rupture, thickening, and degenerative signal alterations. Descriptive statistics and the Mann-Whitney U-test were used for statistical evaluation.

Does molar distalization by the Beneslider have skeletal and dental impacts? A prospective 3D analysis.

Objective: The study aimed to clarify (1) the effect of the Beneslider distalization appliance on maxillary molars (M1+2), (2) the type of tooth movement, and (3) changes in skeletal parameters.

Study Design: Dental distalization paths and transversal changes were measured according to the distance of the pterygoid vertical as well as on the virtualized 3D plaster model.

Results: Distalization of the second premolar (P2; T1 - T2) was 2.

Evaluation of Acute Glial Fibrillary Acidic Protein and Ubiquitin C-Terminal Hydrolase-L1 Plasma Levels in Traumatic Brain Injury Patients with and without Intracranial Lesions.

This pilot study aimed to evaluate the association of plasma ubiquitin C-terminal hydrolase-L1 (UCH-L1), glial fibrillary acidic protein (GFAP), and S100 calcium-binding protein B (S100B) with intracranial abnormalities visible on a computed tomography (CT) scan (CT positive) and injury severity in acute traumatic brain injury (TBI). For these purposes, a cohort of 109 adult TBI patients was recruited within 6 h from the injury event. A hyperacute subcohort of 20 patients who had their blood collected within 2 h from injury was analyzed separately for early acute biomarker levels.

Prognostic factors for long-term results after condylar head fractures: A comparative study of non-surgical treatment versus open reduction and osteosynthesis.

This longitudinal study compared functional, anatomical, and quality of life (QoL) outcomes after closed reduction (CR) versus open reduction and internal fixation (ORIF) of condylar head fractures (CHFs). The aim was to determine predictability of results and to establish prognostic factors for poor outcomes, thus allowing therapeutic decision making between CR and ORIF. All fractures of the non-surgical group were treated by CR with maxillomandibular fixation (CR-MMF) according to an managed analogically.

Defining secure surgical bone margins in head and neck squamous cell carcinomas: The diagnostic impact of intraoperative cytological assessment of bone resection margins compared with preoperative imaging.

Background: Imaging provides crucial staging information for treatment planning of head and neck squamous cell carcinomas (HNSCCs). Despite technical progress in imaging techniques, defining the extent of bone involvement preoperatively remains challenging and requires intraoperative information to control for adequate resection. The intraoperative cytological assessment of the bone resection margins (ICAB) provides information whether bone is infiltrated by carcinoma.

3 T - MRI improves intrameatal cranial nerve detection in CI-candidates.

Background: Cochlear implantation meanwhile is a well established standard therapy in different forms of hearing loss in most ages. Clear depiction of the cochleovestibular anatomy and the cochlear nerve are very important for indication and effectiveness of cochlear implantation. Aim/objectives: Therefore the question raises whether Highfield MRI improves precision of preoperative diagnostic imaging especially along the the intrameatal portion of the vestibulocochlear nerve.

Biomechanical loading test on reconstructed mandibles with fibular, iliac crest or scapula graft: a comparative study.

Advantages and disadavantages of the three most commonly-used bone grafts for mandibular reconstruction are widely known, but biomechanical experimental studies are rare. We have done loading tests on cadaveric mandibles reconstructed with fibular, iliac crest, and scapular grafts using 3 different osteosynthesis systems to detect and compare their primary stability. Loading tests were done on mandibles with grafts from the fibula and iliac crest and published previously.

High-grade supraclavicular soft tissue sarcoma as secondary malignancy after successful treatment of acute myeloid leukemia: case report and literature review.

It is well known that the treatment protocols for hematopoetic neoplasms carry a high risk of long-term oncogenicity. However, few reports have been published of sarcomas as secondary malignancies. An unusual case report of a soft tissue sarcoma appearing as a secondary cancer is presented, with a review of the published data.

Enlargement of the cochlear aqueduct: does it exist?

Our intention was to evaluate whether enlargement of the cochlear aqueduct could play a role in dysfunctions of the inner ear. There is little literature dealing with the question of cochlear aqueduct (CA) enlargement and results of reported radiological examinations are contradictory. Therefore, we decided to analyse 400 high-resolution CT-scans of the temporal bone to examine the diameter of the CA.

Peroneal perforator flap for intraoral reconstruction.

Thin and pliable flaps with long, high calibre pedicles are ideally suited to lining the inside of the mouth. The radial forearm free flap has been our flap of choice until now, but we are unhappy with its potential for complications at the donor site. As an alternative, 30 patients have been treated in our unit with peroneal perforator flaps.

Evaluation of the vessels of the lower leg before microsurgical fibular transfer. Part II: magnetic resonance angiography for standard preoperative assessment.

The peroneal artery is the dominant supply of the osteomyocutaneous fibular flap. It has been shown that there can be anatomical variants that could jeopardise the blood supply to the lower limb during harvest of the flap. To avoid postoperative ischaemia of the lower leg, preoperative evaluation of adequate collateral perfusion is essential.

Cerebral vasculitis mimicking migraine with aura in a patient with Crohn's disease.

Introduction: Whereas extraintestinal manifestations of inflammatory bowel disease in general are quite common, cerebral vasculitis is considered a very rare condition. We present a case of Crohn's disease-associated vasculitis mimicking migraine with aura.

Case Description: A 28-year-old woman with Crohn's disease and known migraine with aura had suffered from daily migraine attacks with recurrent focal neurological deficits for 6 weeks.

High resolution magnetic resonance imaging with an orbital coil as an alternative to computed tomography scan as the primary imaging modality of pediatric orbital fractures.

Purpose: The computed tomography (CT) scan is currently the gold standard in the imaging of orbital fractures. The weak points of this imaging modality, however, include restricted soft tissue depiction as well as the radiation. Both attributes are of particular importance in children because of the high rate of trapdoor fractures and the radiation to the lens.
